Mitt Romney continues to be vague about what he would do about President Obama's new policy of not deporting undocumented students who meet certain criteria -- a policy widely praised by education groups. But on Thursday Romney, the Republican presidential candidate this year, proposed an immigration change that is consistent with the proposals of many education groups, and advocates for international graduate students. He proposed that foreign students who obtain advanced degree in math, science or engineering at American universities should be granted permanent residency. Many experts on international education have said that other countries are becoming more competitive in attracting foreign students because of those nations' willingness to keep foreign talent in the country.
